Kevin O’Leary shares the marriage advice nobody wants to hear – as a married man, I completely agree
Kevin O’Leary’s blunt advice shows that lies, hidden feelings, or financial secrets can quietly destroy any marriage.
Building a strong and lasting relationship takes more than just love. Many couples navigate years of life changes only to find a growing distance between them caused by things left unsaid. Kevin O’Leary, known for his blunt voice on financial and life matters, recently shared some marriage advice that many couples may not think about.

O’Leary is a well-known investor and is often called “Mr. Wonderful” on Shark Tank. Besides his business career, he recently tested his acting skills in the film Marty Supreme alongside Timothée Chalamet and Gwyneth Paltrow. This exciting move into acting highlights his multifaceted talents and adds to his already impressive career.
What is the best marriage advice
In a recent video, he shared a short but powerful piece of advice that every married couple should know. Standing in a bold leopard-print shirt and floral pants, he looked far more relaxed than his usual suit-and-tie persona, but his message was as sharp as ever. He posed a thought-provoking question to his viewers: “What is the best marriage advice I can give that nobody wants to hear?”
He answered, “Tell the truth.” He recognized that telling the truth can be tough, especially when a lie sometimes seems like an easy way to avoid conflict. He added, “So hard to do. But long term, it’s the only road to take.” In his view, the moment a couple starts lying, the relationship is over. In his caption, he explained that while a marriage can survive many hardships, “the minute you start lying, you start destroying trust.”
Reactions
Many people found his stance a necessary reality check on what makes a marriage last. One person wrote, “You’re right, Kevin. One lie means you have to tell a hundred more just to keep it alive.” Once a person starts covering up the truth, they often find themselves trapped in a web of stories that require constant maintenance, which eventually drains the relationship’s emotional energy.
Another person stated, “I think it applies to every aspect of life.” If a person cannot be trusted at home, it is unlikely they are seen as reliable in business or friendships. Reliability is a trait that defines a person’s entire character.
Some shared the long-term damage of ignoring this advice. One woman shared, “My husband has lied to me about one thing or another for 55 years. Results, I never believe what he says, I just agree and go on.” Constant doubt can turn a partner into a stranger, leaving one person to handle the relationship alone.
There was also a discussion about what “truth” really means. One commenter wondered, “Does lying include hiding true feelings instead of talking about them?” Holding back true feelings can be just as harmful as telling a direct lie. It stops a partner from truly knowing the person they’re with.
Not everyone agreed with the idea of total transparency. One person wrote, “I will say the exact opposite, try to lie at least sometimes. If you say what’s on your mind, you can get in trouble.” Some people prefer to keep the peace, even if it means not being completely truthful. The risk is that this calmness is just a surface level and hides deeper issues that need to be addressed.
Why this matters

Being honest is essential for keeping any relationship strong over time. When couples choose to be truthful even about difficult topics or desires for change, they tend to feel much happier in their relationship. A study by the University of Rochester found that expressing the truth leads to better emotional well-being for both partners by reducing the stress of hidden resentment.
For example, talking openly about money is really important for couples, as many arguments occur from financial issues. Hiding spending or debt, often called financial infidelity, creates trust issues that are difficult to bridge. According to a survey, couples who don’t share their financial goals tend to feel less satisfied in their relationship compared to those who are open about it.
When you are in a relationship with someone who lies, you have to prioritize your own sense of reality to keep from feeling lost. Experts suggest getting support from people outside the marriage who can help you stay grounded. If you confront a lying spouse, you should stay on one topic like a broken record to avoid their attempts at distraction or turning the tables. Also, instead of attacking them, speak about your own feelings of fear or sadness. If the honesty isn’t there, you must be willing to walk away from the conversation entirely until they are ready to be truthful.
It’s important to discuss your core values before getting married to prevent the temptation to hide the truth later just to avoid arguments. By being truthful from the start, you create a stronger relationship that can better face the ups and downs of life together.
